Benefit of External Rules and Global Forms?

[jfenter]

I'm still fairly new at using iLogic and wonder what the benefit of global rules and forms are over being locally-stored.  I am working on creating part templates and thought that using a global form would allow me to make changes in the future to all parts created from that template if a global rule/form was used.  Am I correct in that thinking?

I have also found that attempting to make changes to iProperties via external rules does not work.  For example, I have an external rule written to change the material type as: 

SyntaxEditor Code Snippet

If Parameter("material") = "MS" Then
iProperties.Material= "MS"
ElseIf Parameter("material") = "FB" Then
iProperties.Material= "FB"
ElseIf Parameter("material") = "SS" Then
iProperties.Material="SS"
ElseIf Parameter("material") = "SF" Then
iProperties.Material= "SF"
ElseIf Parameter("material") = "BP" Then
iProperties.Material= "M2"
ElseIf Parameter("material") = "CB" Then
iProperties.Material= "CB"
End If

As written, when the prompt in the global form is changed to any of these options, the material type does not change.  If I change the rule from an external rule to a local rule and use "material" as a variable it works just fine.  What am I missing?  

Thanks!
